You can bleed the brakes check for leaks on all your brake cylinders and master cylinder if there is no leaks and the pedal still depresses to the floor then it is usually the master cylinder, if you look under the dash up at the cylinder linkage shaft and see it leaking its bad also peel the carpet down and look for brake fluid.
 
A brake booster has an internal diaphragm . Which uses vacuum as a positive pressure to help with apply pressure to the master cylinder. If you brakes work applying allot of pressure more than likely the booster is bad. you also should here a vacuum leak. If you brake pedal goes to the floor more than likely its your master cylinder
